Google Doodle: Fabulous Microbiologist Hans Christian Gram Turning 166
Google Doodle praised Danish microbiologist Hans Christian Gram on his 166th birth birthday today. Born in Copenhagen on September 13, 1853, Hans Christian found a staining method which is used to recognize and match different types of bacteria. The procedure is used to date even after a century.
Christian Gram began medical school in 1878 and finished in 1883. He received his MD from the University of Copenhagen in 1878, after which he went through Europe to analyze bacteriology and pharmacology.
Christian Gram also operated in the lab of German microbiologist Karl Friedländer, which is when he created his routine. While managing a smear of bacteria with a glass violet stain, accompanied by an iodine solution and organic solvent, he observed variations in the composition and biochemical function of units.
Christian Gram’s verdicts were advertised in a journal in 1884, from where the words Gram-positive and Gram-negative were coined.
He formed a method to discriminate between two major types of bacteria. This technique, the Gram stain, continues to be a conventional method in medical microbiology.
The doodle that acknowledges Gram on his birth ceremony today was drawn by Danish guest artist Mikkel Sommer. The doodle is spelled out in illustrations which show Gram doing an analysis, his round glasses, a lens, and bacteria.
